In certain industries, a damaged piece of equipment is not just an inconvenience—it is a disaster. Whether you are deploying military communications gear to a desert zone, shipping precision tools to an offshore oil rig, or transporting high-end touring equipment across the globe, standard packaging simply will not suffice.
You need armour.
At PottertonPacs, we specialise in the “extreme” end of the protective spectrum. Our range of heavy-duty flight cases is engineered to withstand the harshest conditions on Earth. From crushing weights and severe impacts to water ingress and dust storms, we provide the ultimate barrier between your critical assets and the outside world.
Engineered for Abuse: The Bespoke Heavy Duty Range
As a premier UK manufacturer based in Leicester, we don’t just sell boxes; we engineer survival systems for your kit. Our bespoke heavy-duty cases are built to a specification far exceeding standard transit cases.
We utilise the highest grade materials to ensure structural integrity:
• Rugged Construction: We typically use 9mm or 12mm birch plywood, bonded with high-impact laminates or rigidised aluminium skins that resist puncture and abrasion.
• Reinforced Hardware: Standard fittings are replaced with heavy-duty zinc-plated steel ball corners, recessed butterfly catches, and industrial-grade bracing. This ensures the case keeps its shape even when stacked under immense loads.
• Transport Logic: For heavy loads, we integrate recessed handles, forklift skids, and heavy-duty 100mm castors (with braking systems) to make moving massive weight manageable.
These cases are the industry standard for motorsport teams, broadcast units, and industrial engineering firms who need their gear to arrive ready for action, every single time.

The World’s Toughest Brands: Peli and Storm
For scenarios requiring certified protection against the elements, PottertonPacs is a leading supplier of the world’s most renowned heavy-duty brands.
We stock and customise the full range of Peli Protector, Peli Storm, and Explorer cases. These polymer cases are legendary for a reason. They are:
• Crushproof: You can drive a vehicle over them.
• Waterproof & Dustproof: Rated to IP67, these cases feature O-ring seals and automatic pressure purge valves, making them impervious to water, sand, and dust.
• Chemical Resistant: Safe for use in hazardous industrial environments.
If you need a “buy it for life” solution that is virtually indestructible, the Peli range is the gold standard, and we can supply it with custom interiors to match your needs.
The Secret to Survival: High-Density Foam
A heavy-duty exterior is useless if the contents shatter against the inside of the case. The true science of protection lies in the custom foam insert.
At PottertonPacs, we use advanced CNC routing and water-jet cutting to engineer the interior of your heavy-duty case. For heavy industrial items, standard soft foam is often insufficient as it compresses too easily under weight. Instead, we utilise high-density Plastazote and closed-cell foams.
These materials offer superior shock absorption and “memory,” returning to their shape after impact. We design the foam to cradle your equipment at its strongest structural points, ensuring that even if the case is dropped from a height, the G-force is absorbed by the foam, not your expensive instrument.
Trusted by Defence, Aerospace, and Industry
We have spent decades protecting the equipment that keeps the UK running. From defence contractors needing Mil-Spec packaging to aerospace engineers transporting turbine blades, our reputation is built on reliability.
When the environment is hostile and the cargo is critical, trust the experts. Trust PottertonPacs.
